Connectivity Analysis in Vehicular Networks with Slight Traffic Interference

الملخص EN

This paper analyzes the network connectivity in vehicular networks with slight traffic interference, i.e., small-scale traffic accident.

In this paper, we develop an analytical model for highway scenarios or sparse urban scenarios, where the slight traffic interference can make the vehicles slow down rather than block the traffic flow.

When a traffic accident occurs, it is necessary to inform the nearby vehicles to slow down in order to reduce congestion at the accident location.

Once they pass by, they can return to the normal value.

Consequently, we can divide an entire road into two or three subsections, which helps us to analyze the connectivity performance.

In addition, we analyze the impact of several key parameters on connectivity probability, including vehicle arrival rate, vehicle communication range, length of road, vehicle normal speed, and safe speed.

All analytical results are verified through Monte Carlo simulation experiments.

The simulation results are very close to analytical results, which means that the analytical results are accurate and the analytical model we propose is effective.
